I am very attracted to the color red *no surprise, huh?* So I was drawn to these lines: "With reddened tasteful bliss / Each drop of sweat like blood / They dance around in circles". The color made me look twice, but it is the imagery of the entire scene that kept me there. And the phraseology, "drop of sweat like blood" especially.

I just finished watching the film 'King Arthur' with Keira Knightley and Clive Owen--so I can relate to the vivid battle scenes very visually--and an interesting use of dance hall--the ballet of violence and death, 'clasped,' as you say, 'in steel threads.'
